The Glyderau (a Welsh plural form, also known in English as the Glyders) are a mountain group in Snowdonia, North Wales. The name derives from the highest peaks in the range, Glyder Fawr and Glyder Fach. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Cludair", meaning a heap of stones.
Tryfan North Ridge; visibility declined rapidly. Summited in dense fog, got turned around, and had to partially re-ascend. Missed the turn for Heather Terrace on the way down, so descended the scree slope to Cwm Tryfan. Bit of a spicy day. Lesson: always, always bring the compass!!!
